摘要在當(dāng)今經(jīng)濟(jì)全球化、市場競爭日趨激烈的時(shí)代，新產(chǎn)品的開發(fā)時(shí)間成為企業(yè)能否在激烈的市場競爭中取勝的關(guān)鍵因素。傳統(tǒng)的產(chǎn)品設(shè)計(jì)過程中重復(fù)計(jì)算、重復(fù)建模等工作量很大，一直困擾著產(chǎn)品開發(fā)人員，嚴(yán)重影響了產(chǎn)品的設(shè)計(jì)質(zhì)量和效率。這種現(xiàn)象在凸輪的設(shè)計(jì)中尤為突顯。針對(duì)這一問題，本課題利用Pro/E軟件中的運(yùn)動(dòng)仿真模塊對(duì)凸輪機(jī)構(gòu)運(yùn)動(dòng)進(jìn)行模擬仿真。本論文的主要研究內(nèi)容有：1、溝槽凸輪設(shè)計(jì)2、溝槽凸輪機(jī)構(gòu)的零部件的實(shí)體建模3、溝槽凸輪機(jī)構(gòu)的運(yùn)動(dòng)仿真關(guān)鍵詞：溝槽凸輪實(shí)體建模運(yùn)動(dòng)仿真ABSTRACTInthecompetitiveeraofeconomicglobalizationandincreasinglymarkets,thedevelopmenttimefornewproductbecomeakeyfactortowininthefiercecompetitionmarket.Thetraditionalproductdesignprocessofdoublecounting,suchasrepeatedheavyworkloadandmodelinghavetroubledtheproductdevelopmentstaff,aseriousimpactonproductdesignqualityandefficienct.Thisphenomenonisparticularlyonthedesignofcamhighlights.Addresswiththisproblem,thesubjectofusingthemovementsimulationmoduleofPro/Esoftwareonthecammovementsimulation.Inthispaper,themainresearchcontentsareasfollows:1.Designingthegroovecam2.Modelingthemechanismpartsofgroovecam3.MotionsimulatingofthegroovecammechanismKeyWords:Camgroove,Modeling,MotionSimulation目錄緒論.11.1本文研究的背景.11.1.1我國凸輪機(jī)構(gòu)的研究現(xiàn)狀.11.1.2我國凸輪機(jī)構(gòu)CAD/CAM的研究現(xiàn)狀.11.1.3國外凸輪機(jī)構(gòu)及其CAD/CAM的研究現(xiàn)狀.21.1.4我國凸輪CAD系統(tǒng)存在的問題.21.2本文研究的主要內(nèi)容.21.3本文意義.31.4本章小結(jié).32凸輪機(jī)構(gòu)設(shè)計(jì)分析.42.1從動(dòng)件運(yùn)動(dòng)規(guī)律的選取.42.1.1從動(dòng)件常用的基本運(yùn)動(dòng)規(guī)律.42.1.2從動(dòng)件運(yùn)動(dòng)規(guī)律的選取原則.42.2凸輪機(jī)構(gòu)基本尺寸的設(shè)計(jì).52.2.1凸輪機(jī)構(gòu)壓力角和基圓半徑.52.2.2凸輪機(jī)構(gòu)的偏距.62.2.3凸輪滾子半徑.62.3凸輪輪廓設(shè)計(jì).72.4機(jī)構(gòu)簡介.82.5本章小結(jié).93凸輪機(jī)構(gòu)的實(shí)體建模與裝配.103.1Pro/E軟件簡介.103.2零部件的實(shí)體建模.103.3裝配原理簡介與裝配模型的建立.123.3.1Pro/E仿真裝配原理介紹.123.3.2裝配模型建立.143.4本章小結(jié).174凸輪機(jī)構(gòu)的運(yùn)動(dòng)仿真.184.1計(jì)算機(jī)仿真概述.184.1.1計(jì)算機(jī)仿真的基本概念及特點(diǎn).184.1.2計(jì)算機(jī)仿真技術(shù)在制造業(yè)中的應(yīng)用.184.2Pro/E運(yùn)動(dòng)仿真簡介.194.2.1Pro/E運(yùn)動(dòng)仿真的特點(diǎn).194.2.2Pro/E運(yùn)動(dòng)仿真的基本術(shù)語.204.2.3Pro/
